[Arachnida • 2017] Revision and Cladistic Analysis of the Southeast Asian Leaf-Dwelling Spider Genus Calapnita Simon (Araneae, Pholcidae)

Calapnita bario   Huber, 2017

 DOI: 10.11646/zootaxa.4219.1.1 

Abstract

The Southeast Asian pholcid genus Calapnita Simon, 1892 is revised, with descriptions of 17 new species, five of them in the phyllicola group (Borneo: C. lehi, C. kubah, C. bidayuh, C. bankirai; Malay Peninsula, Sumatra, Java: C. anai), 12 in the vermiformis group (Borneo: C. bario, C. bariengi, C. magaseng, C. dayak, C. lawangan, C. loksado; Sulawesi: C. bugis; Philippines: C. bohol, C. dinagat, C. mae, C. nunezae, C. maragusan). New records are listed for six of the eight previously described species. A morphological cladistic analysis supports the monophyly of Calapnita and of its two previously proposed species groups and presents several new phylogenetically informative characters. New data are presented about ultrastructure and natural history (web, egg-sac, egg parasitism).

[Arachnida • 2016] Spider Diversity and Endemism in A South American Hotspot: 20 New Species of Carapoia (Araneae: Pholcidae) from Brazil’s Atlantic Forest

Carapoia patafina

Abstract

The Atlantic Forest along the eastern South American coast is widely recognized as a hotspot with extreme levels of diversity, endemism, and threat. A megatransect study (2003–2015) focusing on pholcid spiders and covering 48 localities across a large part of the Brazilian Atlantic Forest resulted in 132 morphospecies, of which 81% were new to science. The present paper deals with the species of Carapoia González-Sponga, 1998 collected during this campaign. The endemism level is 100%, i.e. all 26 species of Carapoia in the Atlantic Forest are not known from (and not likely to occur) anywhere else. While few species (all of them with non-overlapping ranges) occur in the most southern and northern regions, the central region (between Rio Doce and Rio Paraguaçu; largely equivalent to what has been called the ‘Bahia refuge’) is characterized by high diversity and up to five species per locality. The following species are newly described (from South to North): Carapoia voltavelha (Santa Catarina); C. macacu, C. divisa (Rio de Janeiro); C. nairae, C. capixaba, C. mirim, C. patafina (Espírito Santo); C. pau, C. gracilis, C. zumbii, C. dandarae, C. marceloi, C. viridis, C. jiboia, C. carvalhoi, C. carybei (Bahia); C. alagoas (Alagoas); C. saltinho, C. abdita (Pernambuco); C. septentrionalis (Pernambuco to Rio Grande do Norte). New records and amendments are given for most previously described Atlantic Forest species.

[Arachnology • 2005] Revision of the genus Spermophora Hentz in Southeast Asia and on the Pacific Islands, with descriptions of three new genera (Araneae: Pholcidae); Aetana from the Philippines, Borneo and Fiji, Suvarna from Thai-Malay peninsula & Khorata from Khorat plateau & Laos

The main aim of the present paper is to delimit ‘true’ Spermophora, i.e. the group of species most closely related to the type species S. senoculata (Dugès). Apart from the type species, only three previously described species are included in this core group (S. estebani Simon, S. paluma Huber, S. yao Huber), together with nine newly described species: S. kerinci, S. tumbang, S. dumoga, S. maros, S. deelemanae, S. palau, S. kaindi, S. luzonica, and S. sumbawa. Except for the Holarctic and anthropophilic type species, all species have limited distributions in Southeast Asia, northeastern Australia, and the Pacific Islands, where they inhabit the leaf litter layer of tropical forests as well as caves. A tight correlation is documented in Spermophora between the male cheliceral apophyses (distance between the tips) and the pockets on the female external genitalia. In addition, three new Southeast Asian genera are described that appear similar to Spermophora but do not share the synapomorphies of the genus: Aetana n. gen. with three new species from the Philippines (A. omayan), Borneo (A. kinabalu), and Fiji (A. fiji); Savarna n. gen., with one new species from southern Thailand (S. thaleban) and two species from Sumatra and Malaysia transferred from Spermophora [Savarna tessellata (Simon) n. comb., and S. baso (Roewer) n. comb.]; and Khorata n. gen., with four new species from Thailand (K. bangkok, K. schwendingeri) and Laos (K. khammouan, K. jaegeri).
